Qhov Tseem Ceeb Qhov txawv - Incineration vs Pyrolysis
Ob qho tib si incineration thiab pyrolysis yog cov qauv ntawm kev sib txuas, cov thermal decomposition ntawm cov teeb meem. Lawv txawv ntawm ib leeg raws li qhov yuav tsum tau muaj oxygen rau cov txheej txheem combustion. Qhov sib txawv tseem ceeb ntawm incineration thiab pyrolysis yog tias incineration yog kev combustion ntawm cov organic teeb meem nyob rau hauv lub xub ntiag ntawm oxygen whereas pyrolysis yog combustion ntawm organic teeb meem nyob rau hauv tsis muaj oxygen.
Dab tsi yog Incineration?
Incineration yog kev sib txuas ntawm cov organic teeb meem nyob rau hauv lub xub ntiag ntawm oxygen. Nws yog ib txoj hauv kev loj ntawm kev rhuav tshem cov khoom pov tseg. Nws yog ib hom kev kho thermal nqa ntawm qhov kub siab heev. Cov txheej txheem incineration converts pov tseg rau hauv tshauv, gases (flue gas) thiab cua sov. Cov cua sov uas tsim los ntawm kev kho mob no tuaj yeem siv los tsim hluav taws xob.
Daim duab 1: Ib tsob ntoo Incineration
Incinerators yog siv nyob rau hauv cov txheej txheem incineration loj. Cov incinerators ntxov tshaj plaws tsis muaj cov kauj ruam ntawm cov khoom sib cais rau cov khoom sib cais uas muaj kev phom sij, loj lossis rov ua dua tshiab. Niaj hnub nimno incinerators yog ntau dua thiab siv tag nrho cov teeb meem muaj txiaj ntsig nrog rau cov pov tseg. Cov incinerators no muaj cov cuab yeej ua kom muaj kuab paug (rau kev ntxuav cov pa taws). Niaj hnub nimno incinerators txo qhov loj ntawm cov pov tseg los ntawm 80%. Lub ntim yog txo los ntawm ib ncig ntawm 95%.
Muaj ntau ntau txoj hauv kev los ua cov txheej txheem incineration:
- Kub pawg - suav nrog cov khoom siv hluav taws kub kub hauv av hauv thaj chaw qhib.
- Hlawv lub thoob - cov khoom siv hluav taws xob tau muab tso rau hauv lub thoob hlau thiab raug hlawv. Txoj kev no tiv thaiv kev sib kis ntawm cov khoom siv hluav taws kub thiab cov tshauv uas ua rau thaum kawg ntawm qhov incineration nyob rau hauv qab ntawm lub thoob.
- Rotary-kiln - Lub tshuab hluav taws xob yog hom incinerator. Cov incinerators no yog siv rau hauv kev lag luam nplai. Nws muaj ntau yam cuab yeej, thiab cov txheej txheem incineration yog ntau tshaj thiab nyuaj.
- Fluidized txaj - txoj kev no suav nrog cov cua kub dhau los ntawm lub txaj xuab zeb kom txog thaum lub txaj fluidized tsim. Tom qab ntawd cov khoom pov tseg tau nkag rau hauv lub txaj fluidized no.
- Tsiv grate - qhov no yog hom incinerator uas siv hauv cov txheej txheem tswj cov khib nyiab hauv nroog. Lub combustion yog ntau npaum thiab ua tiav
Qhov tsis zoo ntawm kev hlawv muaj xws li hauv qab no:
- Incineration txo qis cov khoom siv rov ua dua tshiab vim tias kev hlawv yooj yim dua thiab pheej yig dua li kev rov ua dua tshiab.
- Incineration tso tawm gaseous Cheebtsam xws li carbon dioxide (CO2).
- Incineration emits cov khoom tsim nyog kawg.
- Kev ua txhaum cai tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv.
YPyrolysis yog dab tsi?
Pyrolysis yog kev sib xyaw ntawm cov organic teeb meem thaum tsis muaj oxygen. Qhov no yog thermal decomposition ua nyob rau hauv ib qho inert cua xws li nyob rau hauv lub xub ntiag ntawm lub tshuab nqus tsev pa. Cov tshuaj muaj pes tsawg leeg ntawm cov khoom yog hloov los ntawm cov txheej txheem no, thiab cov txheej txheem yog irreversible.
Feem ntau, pyrolysis ntawm cov khoom siv organic ua rau tsim cov khoom tsis sib xws nrog rau cov khoom muaj cov khoom seem thiab cov tar. Cov txheej txheem no muab cov khoom kawg hauv cov theem khoom, theem ua kua thiab roj theem ib yam. Lub pyrolysis ua tiav ntawm qhov kub siab tshaj 430 ° C. Carbonization yog ib hom pyrolysis uas tawm hauv cov khoom seem uas nplua nuj nrog carbon.

Kev siv pyrolysis yog raws li hauv qab no:
- Ethylene ntau lawm
- Production of tar
- Kev tsim khoom ntawm biofuels los ntawm biomass.
Dab tsi zoo sib xws ntawm Incineration thiab Pyrolysis?
- Ob qho tib si incineration thiab pyrolysis suav nrog kev hlawv cov ntaub ntawv.
- Ob txheej txheem tsim cov roj av ua cov khoom kawg.
